A Rare Case of Pneumobilia Caused By Ingestion of Methyl Ethyl Ketone Peroxide

Introduction: Methyl Ethyl Ketone Peroxide (MEKP) is a highly toxic substance which is used as a solvent. MEKP causes morbidity and mortality by leading to severe metabolic acidosis, kidney failure and liver failure due to necrosis of the hepatocytes. In this case report we aim to discuss the clinical and radiological findings of an accidental MEKP poisoning. Case Report: A 64-year-old male was referred to our clinic after accidentalingestion of a corrosive substance. The vital signs were normal and fluid treatment was started. The patient was hospitalized after the computerized tomography scan (CT) showed severe esophagitis and pneumobilia. The CT scan revelaed regression on the 3rd day of hospitalization. The patient was discharged by his own will on the eighth day before providing total recovery. Conclusion: Unlike other corrosive substances, MEKP may cause intra-abdominal free air such as pneumobilia. An early CT scan helps to evaluate the need for emergency surgical intervention and may prevent patients from unnecessary surgery.
